A traffic signal light device (100) includes a spread window (140), a Fresnel lens (130), and an LED module (120) for emitting light. The light emitted by the LED module passes through the Fresnel lens and to the spread window. The LED module is disposed at a position that is offset from an axis of the spread window that passes through a center of, and is perpendicular to, the spread window. The Fresnel lens can have a saw-toothed pattern of teeth formed as concentric circles on one surface of the Fresnel lens sharing a common center, where the size or height of the teeth vary. The spread window can have a plurality of protruding cells of varying size on a surface of the spread window.
摘要:
Fixing strip (1) for a light-source band, which light-source band (100) includes light-emitting light sources (101) and a device for conducting current to the light sources (101), which fixing strip (1) is at least partly transparent and/or photoconductive, and includes a space (2) for at least one light-source band (100). The fixing strip (1) includes a light-storing substance (5), which emits light for at least a certain time after the light sources (101) of the light-source band (100) arranged in the space (2) are not in operation.
摘要:
A lens system includes multiple light emitting diode sources. The lens system further includes optics configured to capture and direct light from the multiple light emitting diode sources. The system generates a 360° horizontal beam pattern and a predetermined vertical beam pattern.

The invention relates to an indicator lamp, in particular for an electromechanical command device. The indicator lamp comprises a housing (1) and a light source (2), which is arranged in said housing (1) and emits light when supplied with energy. Furthermore, a lens arrangement (5) is provided, comprising a first lens unit (6), which is arranged in the propagation direction of the light emitted by the light source (2) and is built such that light beams emitted by the light source (2) exit substantially parallel from a side of the first lens unit (6) that faces away from the light source (2). According to the invention, the lens arrangement (5) comprises a second lens (7), which is arranged on the side of the first lens unit (6) that faces away from the light source (2) and is built such that some of the light beams exiting from the first lens unit (6) are directed with respect to the propagation direction towards a transparent side surface of the housing (1).
摘要:
A light emitting diode (LED) light with a corrugated reflective surface is disclosed. The corrugated reflective surface reflects and diffuses light beams emitting from a light source having at least one LED. The corrugated reflective surface can be concavely curved. The curvature and the corrugations of the reflective surface can be designed by an equation to achieve a specified beam spread.
摘要:
A light emitting diode (LED) light unit is disclosed. For example, the LED light unit includes at least one support plate having one or more inner openings. At least one LED array may be coupled to an LED board. The LED light unit also includes at least one heat pipe coupled to the LED board, wherein said LED board is coupled to the at least one support plate.
摘要:
The present invention is directed to a beacon light with a light emitting diode (LED) optic. In one embodiment, the LED optic includes at least one LED comprising an LED plane, a first reflector positioned above the LED plane and comprising a curved cross-section, wherein the at least one LED is positioned approximately 90 degrees with respect to an optical axis of the first reflector and at least one second reflector positioned above the LED plane.
